COUPLING FOR UNITING STREAMS FROiVlFlRE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 276,131, dated April 17, .1883.

Application filed November 18, 1881.

To all whom it may concern:

(No model.)

and its attached parts to illustrate my inven- Be it known that I, CORNELIUS CALLAHAN, tion, and Fig. 2 a partial side elevation and of Chelsea, Massachusetts, have invented an Improvementin Couplings for Uniting Streams 5 from Fire-Engines, of which the following description, in connection with the accompanying drawings, is a specification.

Couplings for uniting streams from fire-engines as now commonly made for fire-department equipment are composed of a triangular cast-metal box. This box has at one end two or more inlet collars or water-ways, and at its other end one outlet collar or water-way. The inlet-collars are screw-threaded to have united 1 with them two or more lines of hose-pipes leading to one or more fire-engines, while the outlet-collar permits the water in the coupling to be discharged therefrom as one stream through a discharge-pipe. This coupling, commonly O laid upon the ground and tied or secured to a bar driven therein, has connected with its outlet-collar a stiff rigid pipe or nozzle which is very hard to hold, and when the coupling is to be moved or turned to change the direction of the stream requires a very considerable expenditure of strength.

I am aware that couplings of this sort have been provided with swiveling discharge-pipes to change the direction of the stream without 0 turning the coupling. In this my invention I have provided the coupling with a pivoted pintle, which, when the couplingis in use, is placed in a hollow step connected with a base-board or foot-piece provided with a hole through which a metal spike may be driven into the ground to hold the foot-piece stationary.

A coupling with a pintle, such as described, may be readily turned in any desired direction, horizontally and up and down, and conse- 0 quently the rigid discharge-pipe in connection therewith may be placed in any position the resultant of such n'iovements; but it will be noticed in this my invention that the water ontering the coupling through two or more collars at its large end is discharged therefrom through a single outlet-collar at one of its corners, and substantially in a direct line, so as not to impede theoutward flow of the water by abrupt turns between the inlet and outlet.

Figure 1 represents in front viewa sufficient portion of a coupling of the class referred to section of the same.

The base a, preferably astron g board or footpiece, may be secured in place on the ground by means of a headed and sharpened bolt, m, driven through a hole in the base and into the ground. The base a has attached to and rising from it a hearing or step, I), open at top, in which is placed the pintle c, pivoted at 01 upon an ear, 0, of the coupling f. The coupling f, having its pivoted pintle inserted in the step b, may be turned freely up and down on the pivot d and be rotated horizontally by reason of the pintle c in the step b. The coupling, supported as described, may be readily turned in any desired direction at the will of the tireman holding the discharge-pipe g, which in practice will be a rigid metal pipe, having any usual removable end piece, h, through which the water forced into the coupling from the three lines of hose 2' j It will be discharged.

The pipe g, in practice, will be provided with suitable loops near its outer end, to serve the purpose of handles. The pipe g may be ofany desired length. in practice it will be about thirty inches long.

Instead of the base a, (shown as a base-board or foot-piece,) the step b may be provided at bottom, if desired, with a broad metal foot or base and an attached spike.

When notin actual use the pintle will be removed from the step.

I claim--- The couplingf, for uniting the streams from fire-engines, provided with ears 0 and the pintle c, secured by a pin, (1, in said ears, to permit the vertical movement of said coupling, combined with the hearing or step b to receive 0 said pintle to permit horizontal movement of said coupling and its disconnection from its support, the base a, and anchoring devices m, all constructed and arranged to operate substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CORNELIUS CALLAHAN.
